Description

This PR fixes a bug where the height prop of the XAxis component in BarChart.tsx could result in a NaN value, causing a warning message ("Received NaN for the height attribute") and don't rendering bar charts in react 19.

Problem:
The original code (height={rotateLabelX?.xAxisHeight}) was susceptible to returning NaN in certain scenarios.

Solution
This PR introduces a default value (0) using the nullish coalescing operator (??). This ensures a valid height is always set, preventing the warning and potentially improving rendering of BarCharts.
